Listen to entire message the personal physician left before 911 was called

Below:

According to law enforcement sources, on the day Michael Jackson died, his personal physician, Dr. Conrad Murray made three phone calls: One to his office in Las Vegas, one to a friend, and one to a patient, Bob Russell. Russell did not answer; voicemail picked up. Excerpts from that voicemail were first heard publicly on Feb. 5, 2010 on Dateline NBC.

Now that Dr. Murray has been charged with involuntary manslaughter by the Los Angeles District Attorney, that voicemail could play a significant part in any trial for two reasons: the timing of the call and Dr. Murray’s demeanor when he made the call.

The time stamp on the voicemail is 11:54 a.m. PT. That’s about 30 minutes before the 911 call was made from Michael Jackson’s house. In all, according to court documents, Murray was on and off his cell for 47 minutes starting at 11:18 a.m. Was he sitting there watching Michael Jackson the whole time? Or was he focused on the conversations he was having? Was he even in the same room?
